【Abstract】 As an important safety accessory of elevators, the speed limiter plays a crucial role in protecting passengers’ lives. However, the traditional elevator speed limiter, which triggers actions through centrifugal weights, has many problems such as complex mechanical structure and insufficient sensitivity. To address these issues, a new type of elevator speed limiter based on hydraulic braking and electromagnetic clamping was designed. It uses proximity switches to measure the speed of the elevator car. The measurement and control system centered on the STM32 microcontroller controls the actions of the hydraulic braking mechanism and the electromagnetic clamping mechanism to limit the speed of the speed limiter wheel. This new type of speed limiter has the advantages of precise speed measurement, reliable braking, rapid action, and adjustable clamping force, and has good promotion value and market prospects.更多还原
